Santa Fe has a low nose and a 3 - chime horn on the left side of the hood behind the cab. Southern has a high nose, a 5 - chime horn on the cab, and a bell detail on the short hood. Union Pacific has a low nose, a 3 - chime horn between the 2nd and 3rd radiator fans, and a winterization hatch.

Using your Atlas HO scale SD - 24 Low Nose locomotive is easy. First, connect it to your DCC system to enjoy the sound features. When operating, make sure the track is clean to ensure smooth running. Keep it away from strong magnetic fields as they might interfere with the DCC and sound functions. For maintenance, gently clean the locomotive with a soft brush to remove dust. Periodically check the wheels for any debris or wear. Store it in a dry and cool place when not in use to prevent damage to the paint and internal components. If you notice any issues with the sound or movement, refer to the user manual or contact Atlas customer support.
